Loop Specifications

 


TYPE 100


 

General Description– 14-gauge TFFN wire is encased in a 1/2″ OD Polypropylene /Tube/ Nylon casing which is then injected with an asphalt rubber compound.

Wire– 14-gauge TFFN standard.

Loop casing – 2250 psi Polypropylene flexible hose – Approximate weight 3.80 per 100 foot OD 1/2″, ID .275″, wall .05″

Tees – SCH 80 CPVC Tees Glued and Sealed with adhesive Medium Duty Shrink. These are the toughest TEE on the market

Asphalt – Rubberized asphalt protects wire from any physical damage.

Detection – Detection height is determined by one half the distance of the shortest leg of a loop. Variables apply, i.e.: steel in concrete, etc.

 


TYPE 200


 

General Description– 14-gauge TFFN wire is encased in a 1/2″ OD Nylon 11/Tube/ Nylon casing which is then injected with an asphalt rubber compound.

Wire– 14-gauge TFFN standard.

Loop casing – Nylon 11 – Approximate weight 3.80 per 100 foot OD 1/2″, ID .275″, wall .05″

Tees – Black/white polypropylene tees. Locking tees guarantee no separation.

Asphalt – Rubberized asphalt protects wire from any physical damage.

Detection – Detection height is determined by one half the distance of the shortest leg of a loop. Variables apply, i.e.: steel in concrete, etc.

Construction process – The loop is made up of one continuous wire. 6′ x 6′ or larger loops come standard with 3 turns of wire, smaller loops have 4 turns of wire (smaller gauge wire may be substituted in loops with 4 or more turns). Loops are designed with excess wire in them to accommodate expansion and contraction. Loop lead-in wire is twisted a minimum of 3 times per foot to assure no false detection. Loop lead-in includes 5′ of wire extended past the casing. Extra wire is available upon request. Loop casing is injected with asphalt rubber as a sealant to prevent the entrance of water and the movement of wires within the conduit.

Customization: Loops can be ordered in any size, shape or style:

Rectangular
Quadruples
Round
Square

Diamond
Assemblies of
2, 3 or 4 loops

Home runs can be ordered in any length and are sealed to prevent water absorption. Outside
diameter is 1/2″ and is flexible enough to be coiled up into a junction box.

Warranty: DuraLoop comes with a ten-year
warranty against any manufacturer defect.
